The Scot admits that not focusing on the Games in the Chinese capital was his big regret of the season that included reaching the final of the US Open.

Murray was expected to challenge for a medal in China, but suffered a surprise first round exit at the hands of Taiwan's Lu Yen-Hsun.

Murray conceded his approach to the tournament was "unprofessional" but has promised to make up for what he called his biggest disappointment of the year in London in four years' time. 

He said: "I wish I'd played much, much better at the Olympics.

"I was very disappointed and everyone around me could see by the way that I was afterwards that I wanted to play better. 

"I was disappointed with myself, but I came straight from Cincinnati, whereas most of the other athletes had been in China for a few weeks and had time to get adjusted to the conditions."

The last Briton to win the men's singles title at the Olympics was Josiah Ritchie, who triumphed at the 1908 Games in London.

Murray said: "I [will] prepare for the Olympics better next time.

"I realise how big a deal it was."
